Abstract
A system and method are provided for discriminating the nature of traffic flowing through a computer network. Various types of traffic are distinguished. For example, traffic sourced by a software application that generates them may be distinguished. The problem of detecting malicious traffic either originating outside a target network, or inside a target network from a compromised computer is addressed, as is the problem of distinguishing malicious traffic from legitimate web surfing or other applications activity. Traffic distinctions are made based on signal envelope characteristics in such manner as to preserve robust performance even when the subject traffic is encrypted.
